i own a pair of sennheiser HD490's there a good price and depending on where u libe u'll get a good deal, i live in england and got them for £35 when they should have been £50 there very well made and unlike alot of the sennheiser there very light weight and comfortable at the same time, they've got a good honest reproduction in sound, very little colouring, mayby slight warmer and they cope with the bass frquencies better than some i've tried,,
your gonna get loads of different opinions
if you want to get good advice go to
http://www.minidicsussion.com
i got mine for my minidisc and they work very well for my bass
the best advice will come from the guys there cos they know the audio equipment !!
but my best advice is: if your not too sure go to a good audio centre and try them all, everyone with different genres of music not, the very best of level 42 cos that's what the have in , try different sound conditions and where them for a bit,, but like u have found the sennheisers and grado's of this world do what they do the best
hopt that helps
